+Subject: stage-cogl: Fix buffer_age code path
+
+Currently we where checking whether the damage_history list contains
+more or equal then buffer_age entries. This is wrong because we prepend
+our current clip to the list just before the check.
+
+Fix that to check whether we have more entries instead of more or equal.
